Abstract

The present application provides ternary and quaternary azeotrope or azeotrope-like compositions comprising perfluoroheptene and two or more additional components, wherein the additional components are present in the composition in amounts effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene. Methods of using the compositions provided herein in cleaning and carrier fluid applications are also provided.

Claims (29)

1 . A composition, comprising:

i) perfluoroheptene;

ii) n-heptane; and

iii) a compound selected from tert-butyl acetate and isopropyl acetate;

wherein each of the n-heptane and tert-butyl acetate or isopropyl acetate are present in the composition in amounts effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene.

2 . The composition of claim 1 , wherein the perfluoroheptene comprises about 90 weight percent perfluorohept-3-ene and about 10 weight percent perfluorohept-2-ene.

3 . The composition of claim 2 , wherein the composition comprises perfluoroheptene, n-heptane, and tert-butyl acetate, wherein the n-heptane and tert-butyl acetate are each present in the composition in amounts effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene.

4 . The composition of claim 3 , wherein the composition consists essentially of about 80 to about 99.8 weight percent perfluoroheptene, about 0.1 to about 10 weight percent n-heptane, and about 0.1 to about 10 weight percent tert-butyl acetate.

5 . The composition of claim 2 , wherein the composition comprises perfluoroheptene, n-heptane, and isopropyl acetate, wherein the n-heptane and isopropyl acetate are each present in the composition in amounts effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene.

6 . The composition of claim 5 , wherein the composition consists essentially of about 80 to about 99.8 weight percent perfluoroheptene, about 0.1 to about 10 weight percent n-heptane, and about 0.1 to about 10 weight percent isopropyl acetate.

7 . A composition, comprising:

i) perfluoroheptene;

ii) HFC-4310mee; and

iii) trans-1,2-dichloroethylene;

wherein the HFC-4310mee and trans-1,2-dichloroethylene are each present in the composition in amounts effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene.

8 . The composition of claim 7 , wherein the perfluoroheptene comprises about 90 weight percent perfluorohept-3-ene and about 10 weight percent perfluorohept-2-ene.

9 . The composition of claim 8 , wherein the composition consists essentially of about 0.1 to about 25 weight percent perfluoroheptene, about 30 to about 40 weight percent HFC-4310mee, and about 40 to about 50 weight percent trans-1,2-dichloroethylene.

10 . The composition of claim 7 , further comprising methanol, wherein the HFC-4310mee, trans-1,2-dichloroethylene, and methanol are each present in the composition in amounts effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene.

11 . The composition of claim 10 , wherein the perfluoroheptene comprises about 90 weight percent perfluorohept-3-ene and about 10 weight percent perfluorohept-2-ene

12 . The composition of claim 11 , wherein the composition consists essentially of about 0.1 to about 25 weight percent perfluoroheptene, about 30 to about 40 weight percent HFC-4310mee, about 40 to about 50 weight percent trans-1,2-dichloroethylene, and about 0.1 to about 5 weight percent methanol.

13 . A process for dissolving a solute, comprising contacting and mixing said solute with a sufficient quantity of the composition of claim 1 .

14 . A process of cleaning a surface, comprising contacting the composition of claim 1 with said surface.

15 . A process for removing at least a portion of water from the surface of a wetted substrate, comprising contacting the substrate with the composition of claim 1 , and then removing the substrate from contact with the composition.

16 . A process for dissolving a solute, comprising contacting and mixing said solute with a sufficient quantity of the composition of claim 7 .

17 . A process of cleaning a surface, comprising contacting the composition of claim 7 with said surface.

18 . A process for removing at least a portion of water from the surface of a wetted substrate, comprising contacting the substrate with the composition of claim 7 , and then removing the substrate from contact with the composition.

19 . A process for dissolving a solute, comprising contacting and mixing said solute with a sufficient quantity of the composition of claim 10 .

20 . A process of cleaning a surface, comprising contacting the composition of claim 10 with said surface.

21 . A process for removing at least a portion of water from the surface of a wetted substrate, comprising contacting the substrate with the composition of claim 10 , and then removing the substrate from contact with the composition.
